> I created a subclass from FlinkKafkaConsumerBase and wanna add some logic in
> checkpoint snapshot. I failed to do it because methods from
> CheckpointedFunction interface in FlinkKafkaConsumerBase are set to final.
> understand that these methods are set to final because offsets are required
> to hold and commit, so they do not want to be overridden by subclasses. Can
> we provide an additional abstract method to provide subclasses for their own
> state related operations? Call it in then end of final method default logic
> is emtpy.
